CLOSURE non FILLER ornnmes.

Application filed J' anuary 29, 1926. Serial No. 84,578.

This invention relates generally to closures for filling orifices while it has more particular reference to valvular caps embodying a plug valve interposed cross-Wise of the tiller passage. f

The primary object of this invention is to provide a novel closure of the typified character which may be readily applied to storage tanks and other containers, with provision of free access for filling purposes; while when closed escape of the contents or vfumes arising therefromis efi'ectively prevented.

Another-object is to provide a valvular closure, of the kind above referred to, which is simple to construct, cheap to manufacture, andwithalvery effective in use.

IVith the foregoing and other objects in view, this invention embraces certain novel features of construction, combinations and arrangements of parts, hereinafter fully described; typically illustrated in the accompanying sheet of drawings; whereas the real essence and scope thereof is tersely defined by the appended claims.

In the drawings Fig. I is a rear end view of t Conventional type of automobile havingmy novel closure applied to the gasolinetank thereof.

Fig. II is a perspective view of their proved closure for filler openingsper se, in closed position.

Fig. III is a similar View showing the device in open position.

Fig. IV is a perspective view of the stationary portion of the closure device.

Fig. V is a similar illustration of' the movable member or plug.

,Fi VI is alongitudinal section through the device; and, 1 I

Fig. VII is a transverse section taken substantially as indicated by the arrowed lines VIIVII on, the preceding View.

Referring more in detail to the accompanying drawings it will be observed that my novel closure for filler openings comprises a stationary member or casing,'co1 n prehensively designated by the numeral 8, and a relatively movable portion or plug similarly indicated by the reference 9. The member or casing S convenien'tlyalthough not essentially-embodies a cylindrical body having a slightly tapered bore with one end closed-in by an integral wall ll as the art.

well as including a somewhat enlarged ottset or base12 havmga through passage 13 concentric with an inlet open ng 14: 1n the opposed wall of said cylindrical body. In-

cidentally, the through passage 18 and inlet opening 14 may be polygonal in contour so as to afi'ord a maximum filling aperture; and, by way of example only, I have accordingly illustrated the same as hexagonal.

The olfset or base 12, it will be remarked, is conveniently formed with an annular recess l5-for accommodation of a suitable gasket, not shown whereby. a concentric neck orextension 16 obtains, for a purpose later on specified; while it is screw-threaded at 17 to en 'a 'e .a corres ondin thread D b b about the customary filler-opening nipple 18 of an automobile gasoline tank.19 for instance, as typically exemplified in Fig. 1.

tank 19, andwith alproviding an efl'ec- .tive fit idand gas-tight seal'at the] nipple connection 18. i

As a means effective .to lock the device against illicit removal Ianay employ one or more set screws 21, passed through a t pp pening epem g i Out flange 22: of the annular "'recess' said screw or screws being subsequently sealed i any Beferringnow to themovable portion or plug 9, it will be seen that the same embodies a semi-cylindrical shell 23, conformcone d to the taper of the cylindrical body 10, with integral end pieces or walls 2a,.25, respectively. Furthermore, the shell '23 is, provided with a port. or aperture 26 of complemental configuration to that of the through passage. 13 hereinbefore referred to, and with which it is adapted to register w hen' the closure device is in the open position as later on explainedj Attached" to the outer end wall 25, is a separate back piece 27 having an integral undulate 'projection or pair of diametrically aligned manip[dating-wings '28 whereby the plug 9 "is t urned; as 'well as an arcuate segmental plate or apron 29 which serves as a cover of the well-known ways common to for the inlet opening 14 when the plug valve is in the closed position, as best shown in Figs. VI and VII. The aforesaid back piece'27 is, conveniently, attached to the end wall through the mediumof an integral embossinent thereon engaging an axial aperture 31 in the contiguous end wall 25; said einbossinent 30 being formed with a co-extending lip flange 32 which is appropriately swedged over, as shown in Fig. VI, to rigidly connect the parts 27, 25 together in an obvious manner.

As best shown in Figs. VI and VII, it will be seen that the end wall 24 of the plug valve 9, opposite that attached to the back piece 2'7, is axially apertured at 33 to clear a concentric boss 34 inwardly projecting from the casing end wall 11. This boss 34 is axially bored and tapped to receive the correspondingly threaded end of a shouldered retainer screw 35, intermediate the head 30 whereof and the plug valve end wall 24 there is interposed a star spring 37, whereby the plug valve 9 is always held in fluid tight relation to its seat in the cylindrical body 10. The aforesaid screw head 36 is, conveniently, provided with a series of radial notches or holes 38 for application of an appropriate tool in assembling, disassembling or adjusting, the plug valve 9 in an obvious manner. Furthermore it is observable that, by virtue of the location of the screw wholly within the device, it is concealed against observation from the exterior and in a measure protected against illicit tampering. V

In order to limit movement of the plug valve 9, as well as to arrest the same against displacement by jarring or the like, I form an arcuate recess 39 in the outer face of the innerend Wall 24 thereof, as best shown in Fig. 5; said recess being'ob'viouslyconcentric with the axis of the plug. Fitted in the recess 39, and adjacent one end thereof, is a coned stop 40 which, in conjunction with a similarly shaped stop 41 projecting inwardly from the cylinder casing end wall 11, serves to limit rotary motion of the plug 9; whereas, the stop 41 is adapted to ride over the stop 40 into the limited space intervening the latter and the adjacent end of the recess 39due to the capacity for slight longitudinal movement of the plug valve 9 permitted by the star spring 37-in effecting locking of the plug valve in closed position. Obviously, spring influenced buffer stops may be employed instead of the stops 40, 41, as will be well understood by those conversant with the art without further description herein; while a stop pin 42 is preferably used in connection with the parts 25, 27 to ensure against relativerotation when swedging over the lip flange 32, as will likewise be well understood. 7 j

In use it will be apparent, on reference to Figs. VI and VII more particularly, that when the device is in the closed position that the segmental plate or apron 29 snugly covers the inlet opening 14, while the semicylindrical shell portion 23 of the plug valve simultaneously closes the through passage 13; whereby said device doubly seals the tank 19 against escape of fumes or gas arising therefrom. Concurrently, the port or aperture 26, in the shell portion of the plug valve 23, is located completely out of registration with the through passage 13, and by virtue of the friction fit of the plug 9 superinduced by the star spring 37, seepage of gas or fumes about the casing body 10 is likewise prevented. On the other hand, when the plug valve 9 is given a quarter turn to the left-hand, as indicated by the arrow in Fig. VII, it will be readily seen that the segmental plate or apron '29 isswept clear of the inlet opening 14, with concurrent movement of the aperture or port 26 into concentric registration over the through passage 13. Simultaneously with the movement just described that portion of the semi-cylindrical shell 23-previously closing the through passage 13%13 turned upwardly towards the left of F 1g. VII until the iongitudinal edge 43 thereof substantially aligns with the edge 44 of the casing body 10, whereas the apron 29 occupies the position best shown in Fig. III. Obviously the turning limits of the plugvalve'9 are controlled by the arcuate recess 39 and co-operative stop 41, as hereinbefore set forth; whereas the stop 40 functions to retain said valve closed after the manner described. I

While the design and construction of closure for filler openings herein shown and described is deemed preferable, it is obvious that in reduclng this invention to practice detail changes Wlll arlse in adapting the same for dififerent uses; aecordingly,"the right to all reasonable variations is hereby reserved, provided they are fairly comprehended withinthe scope of the subjoined claims.
